New Polymers: Polyaryleneetherketones

     Polyaryleneetherketones (PAEK) or aromatic polyether-ketones are high heat-resistant aromatic polymers containing ether links and ketone groups in the main chain which are joined together by arylene groups. The main representatives of polyaryleneetherketones are polyetherketone (PEK), polyetheretherketone (PEEK), polyetherketoneketone (PEKK), polyetherether ketoneketone (PEEKK), polyetherether ketoneetherketone (PEEKEK), and polyetheretherether ketone (PEEEK). At present, the CIS countries do not manufacture PEEK. Since the consumption of such products is rather low, import deliveries, especially of PEEK semi-manufactured articles, are also very small.
